The AOA defines an Unsung Hero as "an osteopathic physician who has enhanced the image of osteopathic medicine by living each day as an example of what an osteopathic physician should be. Serving as an outstanding physician and role model, he or she enhances the profession, creates opportunities for current and future DOs, and instills pride in being a DO and a member of the AOA."

Guardians are those who "advance the culture of osteopathic medicine by having served in a local, state or national osteopathic leadership role. A Guardian also demonstrates a strong sense of pride in the osteopathic medical profession and works actively to advance osteopathic medicine with colleagues and the general public."
